jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
const cases = [];
for (let i = 0; i < 65_000; i++) {
let n = Math.floor(Math.random() * 1000 + 1000)
cases.push(Array.from({length:n}, () => Math.random()))
}Ready to run.
